摘要:

Janus颗粒(JPs)是一类新型的具有微米或纳米尺寸、2个半球具有不同化学特性的胶体粒子。 其中,两亲性JPs在其2个半球上分别表现出亲水和疏水的特性,作为一种新型表面活性剂受到广泛的关注。 本文综述了近几年来两亲性JPs的制备方法、表面活性理论、两亲性表征方法及其在乳液聚合中的应用,并探讨了今后的研究方向。

关键词: Janus颗粒, 两亲性, 表面活性

Abstract:

Janus particles(JPs) are a novel type of colloid particles possessing different chemical characteristics at two hemispheres of particles. The size of JPs is usually in the micro- or nano-scale. Amphiphilic JPs have received extensive attention as novel surfactants due to the hydrophobic and hydrophilic feature shown on the two hemispheres of JPs. This paper reviews the research progress in recent years on the preparation, theory, characterization of surface activities, and the application of the amphiphilic JPs. The research interests in future are discussed.

Key words: Janus particles, Amphiphilicity, Surface activity
